MySQL Error 1610: Corrupted Replication Event Detected
Description
MySQL Error 1610 indicates that the replica (slave) server has encountered a malformed or unreadable event within the binary log during replication. This prevents the replica from applying further changes and breaks the replication stream, requiring manual intervention.
Error Message
Corrupted replication event was detected
Known Causes
4 known causesNetwork Transmission Errors
Data corruption can occur during the transfer of binary log events from the source to the replica due to unstable network connections or packet loss.
Disk or File System Corruption
Integrity issues with the underlying storage system where binary log files are stored can lead to physical damage of replication event data.
Abrupt Server Shutdown
An unexpected termination of the source server process while writing to the binary log can result in partially written or corrupted events.
MySQL Software or Configuration Issues
While less common, rare MySQL software bugs or incorrect binary log settings can sometimes lead to improperly formatted replication events.
Solutions
3 solutions available1. Skip Corrupted Event on Slave easy
Temporarily bypass the corrupted event to allow replication to resume.
1
Connect to the slave MySQL server.
2
Stop the slave threads.
STOP SLAVE;3
Identify the problematic event. You might need to examine the slave's error log for more details about the specific event or its position. If the error message provides a specific position, use that. Otherwise, you might need to analyze the relay logs.
4
Execute the `SET GLOBAL` command to skip the corrupted event. Replace `[event_position]` with the actual position of the corrupted event. If the error message doesn't provide a specific position, you might need to use `SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;` and then `START SLAVE;` to try and advance past the error, repeating if necessary.
SET GLOBAL SQL_SLAVE_SKIP_COUNTER = [event_position];5
Start the slave threads.
START SLAVE;6
Monitor the slave's status to ensure replication is progressing without further errors.
SHOW SLAVE STATUS\G2. Re-sync Slave from Master's Current Position medium
Re-establish replication by getting a consistent snapshot from the master.
1
On the master server, obtain the current binary log file and position. This is crucial for a clean resynchronization.
SHOW MASTER STATUS;2
On the slave server, stop the slave threads.
STOP SLAVE;3
Reset the slave configuration to clear any corrupted state.
RESET SLAVE;4
Reconfigure the slave to connect to the master using the binary log file and position obtained in step 1. Replace `[master_host]`, `[master_user]`, `[master_password]`, `[master_log_file]`, and `[master_log_pos]` with your actual values.
CHANGE MASTER TO MASTER_HOST='[master_host]', MASTER_USER='[master_user]', MASTER_PASSWORD='[master_password]', MASTER_LOG_FILE='[master_log_file]', MASTER_LOG_POS=[master_log_pos];5
Start the slave threads.
START SLAVE;6
Monitor the slave's status to verify that replication is functioning correctly.
SHOW SLAVE STATUS\G3. Rebuild Slave from Master Backup advanced
A more drastic but reliable solution involving a full data restore.
1
On the master server, create a full backup. Using `mysqldump` is a common method. Ensure you include replication-related information if possible. Replace `[backup_file.sql]` with your desired filename.
mysqldump --all-databases --master-data=2 > [backup_file.sql]2
On the slave server, stop the MySQL service.
sudo systemctl stop mysql3
Cleanly remove all data from the slave's data directory. **WARNING: This will permanently delete all data on the slave. Ensure you have a valid backup before proceeding.**
sudo rm -rf /var/lib/mysql/*4
Restore the backup to the slave server. Replace `[backup_file.sql]` with the path to your backup file.
mysql < [backup_file.sql]5
Configure the slave to replicate from the master. You will need the master's binary log file and position from the `mysqldump` output (look for `CHANGE MASTER TO` statements within the dump file or use `SHOW MASTER STATUS;` on the master if you didn't use `--master-data`). Replace placeholders accordingly.
CHANGE MASTER TO MASTER_HOST='[master_host]', MASTER_USER='[master_user]', MASTER_PASSWORD='[master_password]', MASTER_LOG_FILE='[master_log_file]', MASTER_LOG_POS=[master_log_pos];6
Start the MySQL service on the slave.
sudo systemctl start mysql7
Verify replication status.
